Well, just to provide an update on this as no-one has offered a solution, I contacted Phase One support for advice, and was told:

"Please uninstall and load 7.1.3, I think you may have better luck with this version with Windows. Then, wait for the next version out to upgrade."

I've now done this, also in the hope of correcting some other issues as well, and no luck I'm afraid. It's not a feature that I desperately need, but for software this costly I'd expect all features to work.

Hi Ian,

Presumably because nobody else experiences this issue. So how could one offer a solution, other than to try the suggestion that Phase One support apparently gave based on your input.

That's what makes it difficult to suggest solutions, you apparently also experience other issues we don't know about. Maybe they are related.

Just a shot in the dark, have you tried disabling "Hardware acceleration" on the general tab of the Preferences? We have to assume you updated your graphics drivers to the latest, as presumably also suggested by Phase One?

Yes I do realise now that it's not a common issue, and that had it have been there would have been some responses. But of course I didn't know that when I posted! The trouble is, of course, that if it's not commonly experienced then finding a solution is likely to prove difficult. My follow up post is more for information really, to those 130 or so viewers.

The "other issues" I mentioned have also been referred to Phase One, and as both responses suggested uninstalling v7.1.4 and replacing it with v7.1.3 I was persuaded to undertake the exercise. And yes, I have tried disabling hardware acceleration, but that didn't make any difference either I'm afraid. They didn't suggest, and I haven't undertaken, updating the graphics drivers. I'll look into that, thanks.

I recently noticed the same behavior when attempting to mask .tiff files that have been through photoshop. I just assumed that this feature is only available for raw files. Works with raw format files from supported cameras.
